Prominence of environmental and anthropogenic agents on the occurrence of coral reef bleaching syndrome and coral diseases

Coral reefs are the most productive ecosystems on Earth. They ensure the conservation of biodiversity and are a live habitat for 25% of all marine organisms. The main relationship on the coral reef is the symbiosis between corals and algae from the genus Symbiodinium (commonly called zooxanthellae). The authors of this publication have characterized and described the factors limiting the occurrence of coral reefs, including: water temperature, salinity, access to sunlight, contamination, physicochemical and hydromechanical parameters of water. Moreover anthropogenic threats to coral reefs have been specified, including diving tourism, ecological disasters (e.g. oil spills) and the development of marine aquaristics. Rapid changes in the basic living conditions are dangerous for corals and their symbionts and may cause the unsuitability of the new environment resulting in diseases such as coral bleaching. Corals bleaching is a disease associated with the break of the coral and algae relationship which results in a coral reef death on a global scale. Awareness of these negative factors, often related to human activity, may allow us to better understand the ecological processes that are the basis of reef functioning and might enable us to prevent and oppose to the changes and ecological recessions of coral reefs.

Pause, Pivot, and Shift: Situational Human Capital and Responses to Sudden Job Loss

How, in the wake of the coronavirus crisis, do workers respond to rapid changes in the labor market? This paper mobilizes existing literature on occupational mobility and job loss to develop a theory of situational human capital in which some workers are better positioned to weather occupational transitions than others depending on the alignment between their skill sets, opportunities, and particular contexts. Previous literature looks at this in the case of “pausing,” when workers, such as women, take time off from work. Relatively less explored but equally consequential are transitions like “pivoting,” in which workers maneuver within their occupations to adjust their practices or platforms in order to keep working, and “shifting,” in which workers change their occupations altogether. Since most government unemployment benefits focus almost exclusively on workers’ pauses, they neglect to support workers as they pivot and shift during periods of labor market instability and disruption. This paper concludes by offering some policy recommendations to fill this gap.

The Rapid Shift from Onsite to Online Teaching – Students’ Perceptions

Recent developments in response to the Covid-19 pandemic have had a substantial impact on students, teachers and content delivery modes around the globe. This paper reports the efforts of the University of Tetovo (UT) in North Macedonia (NM) and Banat’s USAMVB University “King Michael I of Romania” to find rapid and efficient means of switching from direct to remote course delivery while maintaining effective communication. Acknowledging that little space was available for training teachers and learners to prepare for such rapid changes, this study examines how students responded. Applying exploratory research methods, the paper offers a preliminary analysis of the difficulties that learners faced in shifting to online presentation. Qualitative data was collected using student interviews and content analysis (Silverman, 2005) was applied to identify themes, biases and meaning. Convenience sampling among enrolled students in the academic year 2020/2021 at both universities identified a non-random sample of 16 students. The findings of the study revealed that participants faced many difficulties in their venture; however, using various strategies, effective planning and organization, they managed to a certain extent to overcome this situation.

A study of artificial intelligence on employee performance and work engagement: the moderating role of change leadership

PurposeThis paper aims to explore employee perceptions of companies engaged in services and banking of the role of change leadership on the application of artificial intelligence (AI) that will impact the performance and work engagement in conditions that are experiencing rapid changes.Design/methodology/approachThis study has used a quantitative research approach, and data analysis uses an approach structural equation modeling (SEM) supported by program computer software AMOS 22.0. A total of 357 respondents were involved in this study, but only 254 were qualified. In this study, the respondent is an employee of companies engaged in the services and banking sector in the East Java, Indonesia region.FindingsThe results reveal that AI has a significant positive effect on employee performance and work engagement. Change leadership positively moderates the influence of AI on employee performance and work engagement.Originality/valueThe development of this model has a novelty by including the moderating variable of the role of change leadership because, in conditions that are experiencing rapid changes, the role of leaders is essential. After all, leaders are decision-makers in the organization. The development of this concept focuses on studies of companies engaged in services and banking. Employee performance is an essential determinant in the organization because it will improve organizational performance. In addition, the application of AI in organizations will experience turmoil, so that the critical role of leaders is needed to achieve success with employee work engagement.

Kesiapan Generasi Milenial Sebagai Role Model di Era New Normal

<em>In 2020, the year the demographic bonus begins, the millennial generation is in the age range of 20 years to 40 years. This age is a productive age which is predicted to be the backbone of Indonesia's change. However, before achieving the optimization of the demographic bonus which is considered to have a positive impact, Indonesia was first hit by the Covid-19 outbreak with a very fast transmission. Not wanting to linger in uncertainty when the pandemic will end, the Government finally decided to live side by side with Cov19, one of which was by issuing a New Normal policy with the aim of keeping people productive and safe from Covid-19 during the pandemic. Therefore, the community needs a role model that can be used as an ideal role model and example. The millennial generation with all the characteristics and skills they have in this phase is seen as being able to become a role model in facing rapid changes and new orders in society. The approach used is a qualitative approach using literature study methods from books, journals and other sources relevant to the title. The result of this paper is that the productive age of the millennial generation has been in the take off phase, meaning that it can be used as a role model by the community.</em>

Thylakoid grana stacking revealed by multiplex genome editing of LHCII encoding genes

Land plant chloroplasts differ from algal ones for their thylakoid membranes being organized in grana: piles of vesicles paired by their stromal surface, forming domains including Photosystem (PS) II and its antenna while excluding PS I and ATPase to stroma membranes, connecting grana stacks. The molecular basis of grana stacking remain unclear. We obtained genotypes lacking the trimeric antenna complex (Lhcb1-2-3), the monomeric Lhcb4-5-6, or both. Full deletion caused loss of grana, while either monomers or trimers support 50% stacking. The expression of Lhcb5 alone restored stacking at 50%, while Lhcb2 alone produced huge grana which broke down upon light exposure. Cyclic electron transport was maintained in the lack of stacking, while excitation energy balance between photosystems and the repair efficiency of damaged Photosystem II were affected. We conclude that grana evolved for need of regulating energy balance between photosystems under terrestrial canopy involving rapid changes in photon spectral distribution.

Farmers’ Perception towards Transformation of Rice-based Cropping System intoTea Garden

Transformation of agricultural lands into non-farm lands or plantations has got tremendousecological chaos and ripples. Northern part of West Bengal is undergoing rapid changes inrural areas where new opportunities are emerging in the form of demand-driven and market-driven agriculture. Due to persistent low returns from traditional rice cultivation, thetransformation of paddy fields into tea gardens has been a recent trend for this part ofWest Bengal. The present study has been conducted by selecting purposively three blocksfrom Alipurduar district and sixty respondents through random sampling, those who havealready transformed their crop field into tea gardens from these blocks. The farmers’perception towards transformation is taken as dependent variable along with a score offourteen independent variables. The responses are collected through a structured interviewschedule. The study envisaged that the farmers’ education level, number of family membersengaged in the garden, their economic motivation, sources of information, risk orientationbehaviour and distance from the tea processing factory showed significant contributiontowards the transformation behaviour. The future impact of such transformation on theecological dynamics in terms of livelihood, biodiversity restoration and ecological resiliencecan be brought under policy frameworks.

Effect of anisotropy of a single-mode fibre on lightning-induced rotation of polarisation of a light signal in an optical ground wire

A numerical model is constructed for calculating lightning-induced rapid changes in the polarisation state of a light signal at the output of a fibre-optic communication line with an optical ground wire. It is shown that taking into account anisotropy of real optical fibres has a noticeable effect on the shape of the polarisation rotation speed time profile. It is found that the maximum rate of change in the polarisation state and its temporal profile depend on the location of the lightning strike in the fibre span, the magnitude of fibre anisotropy and the direction of propagation of a light wave.
